The couple’s black cocker spaniel puppy is called Lupo, the Duchess told schoolchildren Tuesday.
Kate revealed her puppy’s name during a watercolor lesson she attended at The Art Room, one of the four charities of which she is a patron.
During the visit, a little boy handed Kate a dog stuffed animal, and she asked whether it had a name. When told there wasn’t one, she suggested to name it after her own pup: Lupo.
